SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual
The drive rated current is 100% when
A1-02 = 0 or 1 [Control Method Selection = V/f Control or V/f Control w/
PG]
. The motor rated current is 100% when
A1-02 = 2, 3, or 4 [Open Loop Vector, Closed Loop Vector, or
Advanced Open Loop Vector]
.
Note:
Use this function in conjunction with
S6-01 [OverT Detect Operation Select 1]
. This parameter functions in place of
S6-02 [Overtorque
Detection Level 1]
.

8: Stall Prevent Level During Run
Setting Value
Function
Description
8
Stall Prevent Level During
Run
Enters a signal to adjust the stall prevention level during run if the drive rated current is 100%.
Note:
The Stall Prevent Level During Run is based on the smaller of these two values:
•
Analog input value of MFAI terminal
•
L3-06 [Stall Prevent Level during Run]
Figure 11.77 Stall Prevention Level during Run with Analog Input
■
C: Overload Detection Level
Setting Value
Function
Description
C
Overload Detection Level
Enters the overload detection level.
Note:
Refer to
Overload Detection on page 213
for details.
■
D: Frequency Bias
Setting Value
Function
Description
D
Frequency Bias
Enters the bias value added to the frequency reference as a percentage of the maximum output frequency.
The drive adds the input value from the MFAI terminal set with this function to the frequency reference as the bias
value.
Note:
When you select
d1-01 to d1-16 or d1-17 [Reference 1 to 16 or JOG Frequency Reference]
as the frequency reference, it will disable
this function.
■
E: Motor Temperature (PTC Input)
Setting Value
Function
Description
E
Motor Temperature (PTC
Input)
Uses the motor Positive Temperature Coefficient (PTC) thermistor to prevent heat damage to the motor as a percentage of the
current value when the 10 V analog signal is input.
•
The Positive Temperature Coefficient (PLC) thermistor can be used as an auxiliary or alternative detection
function for issues of drive
oL1 [Motor Overload]
to help protect motors from heat. If the PTC input signal
exceeds the overload alarm level,
oH3 [Motor Overheat (PTC Input)]
flashes on the keypad.
•
The motor is stopped in accordance with the method selected by
L1-03
when
oH3
is detected and in accordance
with the method selected by
L1-04
when
oH4
is detected. Set
L1-05
when false detections of motor overheating
issues occur.
